Sleeping at 10 weeks???

Babies schedules change, it's not because of one night or anything. I don't think your supposed to give them water at 10wks?? Their stomach's are only so big, so you can really only feed them so much formula, you can't "overstuff" them, they'll just spit up the extra, and maybe get a stomach ache. Talk to your doctor, but I don't think they are truely on schedule for a little while, well they're on their own schedule anyway!
